APPARATUS FOR SUPERHEATING VAPORS AND GASES.

SPECIFICATION forming part of Letters Patent No. 485,796, dated November 8, 1892.

Application filed August 25, 1892. Serial No; 444,133. (No model.)

To all whom it may concern:

Be it known that I, Monrrz HONIGMANN, a subject of the Emperor of Germany, and residing at Grevenberg, near Aix-la-Chapelle,

Germany, have invented new and useful Improvements in Apparatus for Superheating Vapors and Gases, of which the following is a specification.

This invention relates to apparatus for super-heating the live steam supplied to steamengines for the purpose of effecting economy in working and is applicable, also, for superheating other vapors or gases. The superheating is effected by means of steam at a very high pressuresay from thirty to fifty atmospheres-which is supplied by a special boiler to a heater constructed as hereinafter described, the condensed steam returning to the boiler, which does not, therefore, require feeding with water, but works continuously with the same water.

The steam or gas to be superheated circulates in the heater, the peculiar construction of which will be described with reference to the accompanying drawings, forming part of this specification, wherein Figure 1 is an elevation showing the in vention applied to superheat the steam for a steam-engine. Fig. 2 is a cross-section of the heater on line a b of Fig. 1, drawn to a larger scale; and Fig. 3 shows a part or scross-seetion of the same, actual size.

The heater A is constructed of two metal plates G G, whereof the inner faces are provided with a series of narrow parallel ribs which when brought together, as shown, form a numberof narrow passages. These plates G G are securely clamped together by means of substantial cast-iron clamping-plates P P, bolted together with the plates G between them by bolts S, so that the plates G form a solid block with internal passages, through which the steam or gases to be superheated are conducted, the plates P being chambered on their inner faces and the high-pressure steam being contained within the chamber provided between the backs of the plates G and the outer plates P. The passages between the ribs of plates G communicate with end chambers K K, common to all.

High-pressure steam is supplied from a boiler 13 through pipes L to the chambers between plates P and G, the water of condensation returning to the boiler by pipes L. The steam or gas to be superheated enters at B into chamber K, passes through the passages of the heater-plates G to the chamber K, and thence by pipe R to wherever it is required-in the example shown to the steamchest D of a steam-engine. The joints between the plates G and between said plates and the outer plates P are made steam-tight and the plates P are made' of suflicient strength to withstand great pressure, and it is evident that this mode of construction excludes any possibility of the parts of the ten millimeters, the plates will not require to be more than about oneand one-half meterlong in order to almost completely impart the heat of the high-pressure steam to the steam or gases to be superheated, thus raising them to a temperature of from 220 to 250 Celsius.

The superheater above described is of special value in conjunction with the steam-engine, as loss by condensation is entirely avoided; but it is well adapted for heating gases for other purposes. The apparatus may of course be varied in construction.

hat I claim as my invention,and desire to secure by Letters Patent, is-

A superheater formed of a pair of metal plates G G, having ribs with intervening narrow channels on their inner faces, clamped together by chambered plates P P, inclosing separate steam-tight chambers between the plates G and the clamping-plates P, wherein high-pressu re steam is conducted, so as to impart its heat to the plates G, which in turn give it up to the gases or vapors to be superheated, which traverse the passages formed between the plates G, as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MORITZ HONIGMANN.
